Features & Benefits

Massive Power in Minimal Space - Delivers 900W RMS from dimensions smaller than most smartphones, enabling powerful subwoofer installations in space-constrained vehicles without compromising performance or installation flexibility.

Factory Integration Excellence - ADEP.3 circuitry prevents diagnostic errors and preserves all factory radio functions including fader controls, while high-level inputs with signal summing eliminate the need for additional line output converters.

Modern Vehicle Compatibility - Start-Stop capability maintains operation during engine cycling, while extended 18V input voltage tolerance ensures compatibility with modern electric and hybrid vehicle electrical systems.

Audiophile Sound Quality - Ultra-low 0.002% THD and 108dB signal-to-noise ratio deliver pristine audio quality that rivals much larger amplifiers, making it suitable for both subwoofer and high-performance midbass applications.

DirectDSP Functionality - Unique bypass mode routes unfiltered signal directly to output stages, enabling perfect integration with external DSP processors and MATCH UPGRADE amplifier systems.

Frequently Asked Questions

Will this work with my factory amplified system? Yes, the ADEP.3 circuitry is specifically designed to integrate with factory amplified systems without triggering diagnostic errors or losing radio functions like fader control.

Can I use this amplifier for speakers other than subwoofers? Yes, the DirectDSP mode bypasses internal filtering, making it excellent for driving high-performance midbass drivers in audiophile installations requiring external crossover control.

How much power will this draw from my electrical system? Maximum power consumption is 80A at 12V, but typical operation draws significantly less. The Start-Stop capability ensures reliable operation during engine cycling.

Will this fit in my limited installation space? At only 46×130×153mm, the UP 1FX is one of the most compact 900W amplifiers available, fitting in spaces where traditional high-power amplifiers cannot.

Is this compatible with MATCH DSP amplifiers? Yes, the mono RCA input and DirectDSP function make it the perfect complement to MATCH M series DSP amplifiers for dedicated subwoofer duties.
